graphs for image pixels

hi, if i have no. of images and i want to display the relationship between them by plots, i wrote code for this task, is this code right for this task?

clc close all clear all

x=imread('10.bmp'); y=imread('20.bmp'); z=imread('30.bmp'); x=x(:); y=y(:); z=z(:); plot3(x,y,z)

if the code right how can i use it with 6 image, and if it's wrong, what is the right code for this task. thank you.

• What is the definition of 'right code'? What is your criteria of comparison? Respective pixels in the images to be of the same value?
• Did you run the code? Did you get any errors? What were they?

yes sir i run it and it's work, but what I meant in (right code) was (is this code useful for this task?).

Again, probably not the answer you're looking for but:

• It's up to you to decide whether this method is useful for you or not - you haven't provided any information about your work so how the community can decide whether what you're doing is right or wrong?
• So maybe start by providing more information about: what is your task? What does it aim to achieve?
• Also you mentioned that you want to 'display relationship between pictures' - this is a very broad term, you really need to be more specific than that - otherwise no-one will be able to help you.

Actually you help me a lot by your Points highlighted above so thank you sir, I was thinking about if I use the plot or meshgrid or surface or ... etc. I will discover whether the pixels are linear or non-linear data.
